Hi all,

are the athlon 64 memory controller registers description publicly available ?

I have a Dell Inspiron 1501 (Athlon 64 Turion X2, ATI RS480 NB, ATI SB600) with
1GB of RAM. Dell specifies that the 1501 can have "up to 2GB of RAM".

Can anybody guess whether it would boot with 4GB of memory, disabling the upper
2GB, and whether I'd be able to re-enable the upper 2GB (preferably mapped
above the 4GB limit: I don't mind, I'm running in 64bit mode and I'd
not lose memory
in the "3GB hole").

Not as far as I know.... the 2GB limit which dell specified is what the motherboard supports..... So the hardware/bios itself will not accept more than the 2GB specified. It has nothing to do with the OS.

Thank you,

Loïc Grenié
